Macho Men Have So-So Sperm

Tradeoff between looks and virility might be at play, says study

(Newser) - Macho guys may attract more women, but the quality of their sperm might not be of he-man standards, a new study suggests.

STD Makes Crickets Mate Like Crazy

Highly contagious iridovirus also causes infertility, death

(Newser) - A newly discovered virus boosts the libido, encouraging those infected—that would be crickets, not humans—to have sex more often and with more partners.
